Music can highlight specific moments, picture cuts, or even lines of dialog. Doing so is called “hitting” or “stinging” a moment. Be very judicial in what moments you want the music to hit. Too much and you risk the music feeling either “Mickey Mousey” (cartoony) or it can lessen the impact of the hits since there are so many of them. It’s like using too many exclamation points when writing. When you get it just right each hit will elevate and/or propel the story very effectively.
